Selexipag treatment in patients with systemic sclerosis-associated pulmonary arterial hypertension in clinical practice, a case series.
Article in Journal of scleroderma and related disorders, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To describe the efficacy and safety in all patients with systemic sclerosis-associated pulmonary arterial hypertension who started selexipag between 09-2016 and 06-2018 in two pulmonary arterial hypertension expert centers. Methods: All patients with systemic sclerosis-associated pulmonary arterial hypertension diagnosed by right heart catheterization and treated with selexipag were included. Every 12 weeks, treatment effect was assessed by (1) the opinion of the expert team and (2) the abbreviated risk assessment, consisting of functional class, six-minute walking distance, and N-terminal prohormone of brain natriuretic peptide level at baseline and during follow-up. Side effects and adverse events were registered. Results: We included 13 systemic sclerosis-associated pulmonary arterial hypertension patients, 10 patients were female, median age (interquartile range) of 68 (58-75) years, median systemic sclerosis disease duration of 7.4 (4.7-13.5) years, and median pulmonary arterial hypertension duration of 4 (2.5-7.5) years. Two patients discontinued selexipag within 4 weeks due to side effects. The remaining 11 patients had a median follow-up duration of 48 (interquartile range = 24-72) weeks. Two patients died (one pulmonary arterial hypertension-related, the other systemic sclerosis-related). According to the expert team, 8 of 11, 9 of 10, and 5 of 7 patients stabilized or improved at 12, 24, and 48 weeks, respectively. According to the abbreviated risk assessment at study end, 3 of 11 patients had 1 low-risk criterion. No previously unrecorded side effects were reported. Conclusion: Adding selexipag to background therapy in a high-risk cohort of systemic sclerosis-associated pulmonary arterial hypertension patients provided sustained stabilization of symptoms with an acceptable safety profile. Improvement was reached in only two of our patients. Further research should focus on systemic sclerosis-associated pulmonary arterial hypertension patients treated with multiple targeted treatments, preferably these patients should be prospectively followed in international registries.
